Force Constants, Infrared Spectrum, and Thermodynamic Properties of TiCl4

The spectrum of gaseous titanium tetrachloride was obtained in the rock salt and potassium bromide regions of the infrared. The thermodynamic functions Cp0, S0, and — (F0—E00)/T were calculated. The orbital valence force field constants were computed, and lead to the conclusion that hybridization changes may be significant in the F2-vibrations.
